Reaction: 3-O-α-D-glucopyranosyl-L-rhamnopyranose + phosphate = L-rhamnopyranose + β-D-glucose 1-phosphate
Other name(s): cphy1019 (gene name)
Systematic name: 3-O-α-D-glucopyranosyl-L-rhamnopyranose:phosphate β-D-glucosyltransferase
Comments: The enzyme does not phosphorylate α,α-trehalose, kojibiose, nigerose, or maltose. In the reverse phosphorolysis reaction the enzyme is specific for L-rhamnose as acceptor and β-D-glucose 1-phosphate as donor.
